Description
Technical field
The present invention relates to a plant growth regulators, be specifically related to a kind ofly the chorista between plant petiole and stem can be promoted to be formed thus promote the plant defoliant composition that plant leaf blade comes off.
Background technology
Plant growth regulator is a kind of ectogenic non-nutritive chemical substance, and it can conduct to site of action usually in plant corpus, just can promote or suppress some link in plant life process with lower concentration, makes it the wish development to meeting human needs; Due to the specific function effect of plant growth regulator, therefore itself and general chemical fertilizer or agricultural chemicals etc. are not quite similar.According to the function of plant growth regulator, it generally can be divided into root-growing agent, Suckering agents, lodging resistance agent, the agent of short fruit, defoliant etc.Wherein, defoliant a kind ofly can promote the chorista self-assembling formation between plant petiole and stem thus promote the growth regulator that plant leaf blade comes off.
Existing plant defoliant generally can be divided into following several:
Single component plant defoliant: existing traditional plant defoliant generally refers to the mixture that some main pharmacodynamics compositions are more single, mainly refers to the compositions such as Thidiazuron; Thidiazuron, chemical name is 1-phenyl-3-(1,2,3 ,-thiadiazoles-5-bases) urea, it is the plant defoliant that in current defoliant, the scope of application is the widest, it is generally applied to the growing of plant fruit later stage, being used for of utilizing it to promote plant leaf blade to come off suppresses the nourishing and growing of plant, thus promotes the reproductive growth of fruit, improves fruit quality; In addition, when the defoliants such as Thidiazuron are when being applied to cotton crop, after its leaf abscission, be just conducive to the mechanical harvesting of cotton, thus improve the quality of cotton further.In existing plant defoliant, Thidiazuron is in use because it directly comes off to the blade of comparatively normal condition, and its defoliation effect is obvious not.
Compound botanical defoliant: the plant defoliant be now mainly made up of Thidiazuron and ethrel for the most frequently used compound botanical defoliant.Ethrel, chemical name is 2 chloroethyl phosphoric acid, and it is also a plant growth regulators, and its Main Function discharges ethene in plant corpus, thus promotes fruit ripen in advance.Above-mentioned compound botanical defoliant is except Thidiazuron can be utilized to play the effect of disleave to plant, ethrel can promote the maturation of fruit, above-mentioned composite conditioning agent is only simple by the combination of effects of two kinds of chemical compositions, and does not have substantial raising for the defoliation effect of Thidiazuron.
Summary of the invention
In view of this, the invention provides a kind of plant defoliant composition, it has synergistic effect, effectively can improve its defoliation effect to plant.
For solving above technical problem, technical scheme of the present invention adopts a kind of plant defoliant composition, and described plant defoliant composition includes the Thidiazuron and sandworm toxin insecticide that weight ratio is 30%-100%, and all the other are auxiliary agent; The weight ratio of described Thidiazuron and sandworm toxin insecticide is 1:1-5.
Preferably, described plant defoliant composition includes the Thidiazuron and sandworm toxin insecticide that weight ratio is 40%-95%, and all the other are auxiliary agent; The weight ratio of described Thidiazuron and sandworm toxin insecticide is 1:1.5-5.
Preferably, described plant defoliant composition includes the Thidiazuron and sandworm toxin insecticide that weight ratio is 45%-90%, and all the other are auxiliary agent; The weight ratio of described Thidiazuron and sandworm toxin insecticide is 1:2.5-5.
Preferably, described plant defoliant composition includes the Thidiazuron and sandworm toxin insecticide that weight ratio is 50%-80%, and all the other are auxiliary agent; The weight ratio of described Thidiazuron and sandworm toxin insecticide is 1:3-4.5.
Preferably, described sandworm toxin insecticide is that at least one is selected from cartap, Cupric sulfate, dimehypo, thiocyclam and bensultap.
Preferably, described sandworm toxin insecticide is that at least one is selected from cartap, Cupric sulfate and thiocyclam.
Preferably, described plant is that at least one is selected from cotton, potato, sunflower, radish and beans.
Preferably, described plant is cotton.
Preferably, described auxiliary agent is that at least one is selected from wetting agent, dispersant, bleeding agent and filler.
Preferably, described plant defoliant composition can be processed into any one in wetting powder, water dispersible granules, suspending agent, aqueous emulsion.
Compared with prior art, its principle is as follows in the present invention:
Plant defoliant composition of the present invention includes the Thidiazuron and sandworm toxin insecticide that weight ratio is 30%-100%, and all the other are auxiliary agent; The weight ratio of described Thidiazuron and sandworm toxin insecticide is 1:1-5.
Sandworm toxin insecticide described in the present invention is a kind of biological species toxin analog with insecticidal action of extraction or Prof. Du Yucang from clam worm, comprises cartap, dimehypo, Cupric sulfate, thiocyclam, bensultap etc.; Sandworm toxin insecticide enters in insect bodies and can be converted into rapidly nereistoxin or Dihydronereistoxin element, this type of plant is acetylcholine competitive inhibitor, have stronger to tag, the conduction such as stomach toxicity and interior suction, have good placement effect to the larva of lepidoptera pest, therefore such material is now widely used as insecticide.Sandworm toxin insecticide is mainly used in preventing and treating the insect on the crop such as sugarcane or paddy rice, but as the crucifer such as Chinese cabbage, wild cabbage, and tobacco, beans, cotton, sunflower, potatoes and other crops kind are responsive especially to sandworm toxin insecticide, be subject to poisoning, thus cause its yellow leaf, easily wither.
Plant defoliant composition described in the present invention just makes full use of above-mentioned sandworm toxin insecticide and easily causes the yellow leaf of certain plants or withered characteristic, makes the good plant defoliant of defoliation effect by mutually composite to itself and Thidiazuron.In plant defoliant of the present invention Thidiazuron mutually composite with sandworm toxin insecticide after, first sandworm toxin insecticide makes the yellow leaf of effective object or withered, at this moment Thidiazuron promotes its cell division at petiole place, thus promote that the chorista between petiole and stem is formed, make its leaf abscission.Plant defoliant of the present invention is when being applied to plant, first the nutriment obtained from axis under the effect of sandworm toxin insecticide due to plant leaf blade reduces, hinder the growth of blade, make it enter the phase of coming off in advance, accelerate the period of the chorista growth between petiole and stem; Then, under the effect of Thidiazuron, jaundice or withered blade will comparatively be easy to come off from plant.
Can be only have above-mentioned two kinds of compositions, i.e. Thidiazuron and sandworm toxin insecticide in plant defoliant composition of the present invention; Except containing except above-mentioned two kinds of compositions, it can also be containing the existing various auxiliary components used as defoliant.
Shared by Thidiazuron described in plant defoliant composition of the present invention and sandworm toxin insecticide, the weight ratio of composition is 30%-100%, and the weight ratio of described Thidiazuron and sandworm toxin insecticide is 1:1-5.When in plant defoliant composition of the present invention, shared by Thidiazuron and sandworm toxin insecticide, the weight ratio of composition is less than 30%, its defoliation effect is undesirable; When the weight ratio of Thidiazuron and sandworm toxin insecticide is less than 1:1 or is greater than 1: 5, its defoliation effect is also undesirable.
Further, plant defoliant composition of the present invention preferably adopts and includes the Thidiazuron and sandworm toxin insecticide that weight ratio is 40%-95%, and all the other are auxiliary agent; The weight ratio of described Thidiazuron and sandworm toxin insecticide is 1: 1.5-5.The present invention preferably adopts above-mentioned embodiment that the defoliation effect of plant defoliant composition of the present invention can be made better.
